mans ear WILLIAM R. MACKLIND,OF MINERAL POINT, MISSQURI.

CENTRIFUGAL SEPARATOR.

Specification of Letters Patent.

To all whom it may concern:

Be it known that I, WILLIAM R. MACK- LIND, a citizen of the UnitedStates, residing at Mineral Point, in the county of Washington and Stateof Missouri, have invented certain new and useful Improvements inGentrifugal Separators, of which the following is a specification,reference being had therein to the accompanying drawings.

This invention consists in improvements in centrifugal separators, andresides particularly in the provision of a peripheral dischargetherefor.

In the drawings, like numbers of reference denote like parts whereverthey occur, and Figure 1 is a top plan view; Fig.2 is an end elevation;Fig. 3 is a sectional view on the line -33, Fig. 2; Fig. 4 is asectional view on the line 44, Fig. 3; Fig. 5 is a top plan view of thecentrifugal chamber, part of the upper shell being broken away; and Fig.6 '1s a transverse sectional view on the line 66, Fig. 5.

' The shaft 1 is journaled at 2 in the base casting 3, and is preventedfrom rising by collar 4. At its upper end, said shaft is journaled inball-bearing collar 5, and adjacent thereto is threaded at 6 to receivethe lower disk or shell 7 of the centrifugal chamber or receiver, saiddisk 7 being thus adapted to rotate with shaft 1. The companion disk orshell 8, which is preferably somewhat concaved and contains an opening9, is fastened todisk 7 by bolts 10, which pass through perforations 11in both disks, springs 12 located between the heads 13 of said bolts andone of the disks and springs 14 located between nuts 15 and the other ofsaid disks tending to ress said disks together, but in an adjustab erelation. The disks 7 and 8, as'is apparent from inspection ofFig. 1,form a long tapering circular wedge, the disk 7 being preferably fiat ascompared to the substantially shallow concavity of disk 8. It is furtherto be observed that the greatest distance between the disks 7 and 8 isexceedingly. small as compared with the diameters of the disks. Theouter edge of each of said disks is circumferentially notched orrecessed, whereby a peripheral groove 16 extending entirely around thecentrifugal chamber isprovided. Said peripheral groove forms ar flaringber 17.

mouth for the-exit, under centrifugal propulsion, of material fromcentrifugal cham- Somewhat more to the center of said disks 7 and 8 thanthe inner edge of the recesses forming the peripheral groove 16, grooves18 in disks 7 and 8 are provided to receive annuluses 19 formed ofrubber or other suitable resilient material. The upper and the lowerannuluses, registering with each other, form a joint betweenthe twodisks impenetrable for liquid and much tighter and closer than would beossible if the touching parts were formed 0 metal. Hollow shaft or pipe20 is preferably an integral continuatlon from the top of shaft 1, oneend of shaftl being. bored to form same. A plurality of branch pipes 23radiate out from pipe 20, and cause the fluid material that enters pipe20 from pipe 24 (leading from any suitable reservoir) to flow away fromthe center of chamber 17 As pipe 20 is integral with shaft 1 so as torotate therewith, the fluid materlal 1s emitted from branch pipes 23with some. force therefrom in the direction of and ejected the openinthat forms between the. dlSkS 7 and 8 ad acent to peripheral groove 16.

'Pipe 20 passes through opening 9 in the shell 8, and in its upper endis journaled in sleeve 25 borne by the cross-p1ece 26 of the main frame27 of the machine, said frame being supported by braces 28.

The pulley 29 is fixed to pipe 20, and 1s driven by belt 30, whichpasses over idlers 31, and, is, in turn, driven by band-wheel 32 mountedports the band-shifter 36, is held in place by one of the braces28 andupright 37. The idlers 31 are supported by arms 38, which pro'ect fromthe braces 28. As will be rea ily understood, the belt-shifter 36 1sPatented Feb. 15, 1910.

on shaft 33, which receives its power from pulley 34. Rod 35, which sup-N used to shift belt 39 from the tight pulley 34 to the loose one 40.Shaft 33 is journaled at one end in standard 41, and at the other incross-piece 42, which extends from one brace 28 to the other. shaft'33,engages gear 44 mounted on shaft Pinion 43, driven by said 45 supportedby standard 46. Beveled gear 47 is, also, mounted on said shaft 45, and

drives beveled gear 48 mounted on shaft v49 supported by bracket 50extending from standard 46. Spur gear 51 is mounted on shaft 49 andactuated thereby, and engages a circumferential rack 52, which extendsentirely around casing 53. Said rack is fastened to casing 53 by bolts54, said rack being on the exterior face of a circular angle-iron.Casing 53 is adapted to rotate around the central drum 55, said'casing53 having an overhanging flange 56 and lip 57 by which it is hung uponcircular bracket 58 rigidly fastened to the central drum 55.

A plurality of scrapers 59 project from casing 53, each arm 60 of eachscraper 59 being fastened by bolt 61, or by other suitable means, toflange 62 projecting from casing 53. As, therefore, casing 53 rotates,the scrapers 59 likewise move circumferentially, and carry with them anymaterial that has fallen upon floor 63, having been conveyed thereto bythe bell 64 and wall 65, which form the receiving chamber into which thesolid matter ejected from the peripheral groove 16 falls after havingbeen separated in chamber 17 by centrifugal motion from the liquid withwhich it was combined when ejected from branch pipes 23 which gave itentrance to chamber 17 from pipe 20.

Floor 63 is supported by standards 66, and, in turn, supports the wall65 forming the outer casing of the receiving chamber. An opening 67 infloor 63 communicates with chute 68, which conducts the separatedmaterial to any desired point.

Oil receptacles 69, connected by pipes to the parts that needlubrication, operate in the usual and well-understood manner.

The flange surrounding opening 9 in disk 8 flares outwardly andupwardly, and terminates in a depending lip 70 that overlaps a lip 71that forms the inner wall of hood 72, which tightly encircles pipe 20,but does not rotate therewith, and is supported in position by rods 73,which are attached to the roof portion of wall 65. A plurality of pipes74 form outlets from the chamber within hood 72, and conduct the liquidthat gathers in said chamber, as hereinafter described, to circular pipe75, which comniunicates with the main discharge pipe 76,

said discharge pipe being governed, in case of need, by cock 77.

. The operation of the machine is as follows Fluid material, such aswhite lead, cyanld slime, whiting, or the like, is allowed to flowthrough pipe 24 into pipe 20, and through branch pipes 23 intocentrifugal chamber 17. Depending upon the nature of .the particularmaterial, pipe 20 and with it branch pipes 23 are simultaneously beingrotated by band 30 and the other mechanism described, or other sultablemeans. The

Speed of rotation will be greater when the weight of the solid mattercontained in the fluid material is less relatlve to the liquid rial iswhiting than when it is white lead.

The constant rotation of pipes 23 throws the fluid material well outinto chamber 17, which is formed between the disks or shells 7 and 8,which themselves are rotating as rapidly "as pipe 20 by reason of theconnection of pipe 20 with shaft 1, to which shaft disk 7 is attached soas to rotate therewith, shell 8 being so attached to disk 7 as to rotatetherewith but to be adjustable vertically relative thereto. Thecontinued rotation of the disks or shells forming the centrifugalchamber 17 results by reason of centrifugal force in the gradualpropulsion of the solid matter which constitutes the weightierconstituency of the fluid material fed into the chamber through pipe 20away from the center of chamber 17 and toward its periphery, where itgradually accumulates, and, by reason of the tapering shape of saidchamber around its circumference, acts as a wedge to force the disks orshells 7 and 8 apart, the centrifugal force being constant and operatingon the material at the periphcry of chamber 17 as well as that near itscenter, and, in addition, forcing new particles against those closest tothe periphery. Thus, the disks or shells 7 and 8, after having been onceforced apart, are, during the continued operation of the machine, keptmeasurably separated so as to form a peripheral opening between samethroughout the entire extent of their circumference, said opening,however, being clogged or blocked with the wedgelike mass of solidmatter that has been separated from the liquid. Said mass, therefore,prevents the escape from chamber 17 of any liquid, but its outerparticles are continuously and gradually discharged through peripheralgroove 16 into the chamber formed between bell 6a and wall 65, saiddischarge being facilitated by the fact that groove 16 flares outwardly.in this connection, it may be observed that while the drawings exhibitthe outlet from chamber 17 as being at the periphery of said chamber,yet some portion of the effect obtained by the preferred form ofapparatus which is illustrated in the drawings would be obtained if anopening or openings adjacent the periphery of chamber 17 were pro vided.lVhen the degree of speed is reduced and the centrifugal forcedecreased, or when the nature of the material treated alters conditions,the amount of space between the edges of disks 7 and 8 will be reduced,partly by the weight of disk 8 and, also, by the force of springs 12 and14. iVhen the material has been ejected from the peripheral opening ofchamber 17 and has falleninto the chamber formed between bell 64 andwall 65, the bottom of the mass rests on floor 63, and is thence removedby the continuous rotation of scrapers 59 and carried to chute 68. Asthe liquid remains near thecenter of chamber 17 and accumulates, itnaturally flows upward through opening 9 into the chamber within hood 72and out through pipes 74 into circular pipe 75, and thence escapes, oris conducted, through pipe 76.
